1-Pyrrolidinepropanamine → 5-[4-(2-fluoro-5-{[(2-fluoro-5-methylphenyl)amino]carbonyl}phenoxy)pyridin-2-yl]-N-(3-pyrrolidin-1-ylpropyl)-1H-pyrrole-3-carboxamide

Participants

Reaction Steps

To a stirred solution of 5-[4-(2-fluoro-5-{[(2-fluoro-5-methylphenyl)amino]carbonyl}phenoxy)pyridin-2-yl]-1H-pyrrole-3-carboxylic acid (150 mg, 0.33 mmol) in 10 ml of anhydrous DMF were added HATU (152 mg, 0.40 mmol) and N,N-diisopropylethylamine (94 mg, 0.73 mmol). The mixture was stirred at room temperature for 10 minutes, followed by addition of N-(3-aminopropyl)pyrrolidine (85 mg, 0.66 mmol), and stirring was continued for another 10 minutes. The mixture was poured into 50 ml of water with vigorous stirring. The precipitates were filtered, washed with water and dried in vacuo to give 5-[4-(2-fluoro-5-{[(2-fluoro-5-methylphenyl)amino]carbonyl}phenoxy)pyridin-2-yl]-N-(3-pyrrolidin-1-ylpropyl)-1H-pyrrole-3-carboxamide as white solid. Yield: 160 mg, 86%.
